Summary
Due to the large number and variability, both in type and concentration, of trace organics in water supplies, a concentration step is required for their analysis. For these reasons, complementary continuous sampling techniques are used by the Laboratory of S.L.E.E. Three types of samplers are used: a composite liquid sampler for the analysis of substances by closed loop stripping, head space. . ., a continuous liquid-liquid extraction cell, and a contactor on macroporous resins or other adsorbents for subsequent elution followed by GC-MS analysis or biological assays. These devices enable composite samples of average concentration to be obtained over one or several days.
Résumé
L’analyse des traces organiques présentes dans une eau brute ou de consommation nécessite une étape de concentration du fait de leur grand nombre et de leur variabi1ité en concentration et en nature. Acet effet des appareillages complementaires de prélèvement en continu ont été mis au point par le Laboratoire de la S.L.E.E. Trois types d’appareil sont décrits ici : Un échantil10nneur d’eau pour 1 ’analyse des substances volatiles par des techniques du type „stripping“ en boucle fermée. espace de tête, etc... Un système continu d’adsorption sur résine macroporeuse ou tout autre support solide et un extracteur liquide-liquide en continu permettant l’analyse par CG-SM ou la réalisation de tests biologiques. Ces appareils permettent d’obtenir un pré1èvement composite de concentration moyenne sur un ou p1usieurs jours.
